IMPROVED FIRE-ARM.'

Specification forming part of Letters Patent No. 16,367, dated January 1,5, 1857.

To all 'whom it may concern.'

Beit known that I, ETHAN ALLEN, of the city and county of IVorcester, and State of the accompanying drawings by the letters of reference marked thereon,in which drawings- Figure 1 shows a section of the improved parts. Fig. 2 is an external side view with the guard-lever and rammer in operative position. Fig. 3 shows a variation in the manner of connecting the parts.v T The same letters refer to 'the same parts in a l.

My improved fire-arm is of that class known as revolvers77 or repeating iire-arms,7 and is constructed as follows: In the revolving piece A (see drawings) make a conical or taper hole to tit the projection B, which is made tapering and solid with the back plate, D, and

extends far enough to give suicient bearing to support the revolving chambers or barrel A steadily, and through which passes the screw C, with its head E on the inside, and, screwing into Afirmly, turns with it, holding it Qn, and yet leaving it perfectly free to revolve. The passage X from the chamber V to tho nipple G is made large and with a` cavity at the baseof thenippleG, in which is placed the conieal valve-piece H, which is made with a smooth conical surface toward the nipple, whose aperture at the base is beveled to [it it, and the face of H toward the chambers is made tinted;

' or the edge ofthe hole maybe iiuted,the valve H being free in the cavity to pla-y against either aperture, as the case may require. The rammer I, which is placed in the piece K, supporting the barrel L, is made with teeth in one side, vin which work cogs on the segment M, madeon the end of the guard-lever N and turning on a pin at O, the other end of theleverN catching over the projection P to hold itin place when not working the rammer. p The other parts (not described) may be. of

lmost any of 'the usual forms of construction,4 merely adapting them to those described; or

those described may be .adapted to other forms,

only preserving their capability to perform certain functions in their operation, as follows:

The support B, being conieahcan be made larger at its base than if straight, and affords great facility in fitting the chambers on it snug, yet free to turn, and allows the cavity for the valve H to be made withoutweakening the body of A materially, and makes a lirm support for A, whereby I am enabled to use a long lever,

N, and give great force to the rammer I' with but little elort of the hand, the lever taking the position shown in Fig. 2 when the rammer is forced down. The force ofthe explosion ot' the cap on the nipple is sufticient to force the valve H toward the aperture leading to the chambers, and thus the fire passes out of the base of the nipple G and round the valve II, the uting of the other side ofthe valve forming passages for it to pass to ignite the charge in 'the chamber, which, when exploding, forces back the valve against the nipple, thus closing the vent and preventing any escape of gas or loss of force of the charge or burning ou't of the nipple.

Instead of the screw C iunning through B, the end of B may be made smaller and have a collar ltted on it, as in Fig. 3, and a screw or screws pass through the sides of A to hold it on, or a groove be used instead ot' a collar, the important features of yB being its being solid or irmly attached to D, securingl stiffness and perfection of tit to A.

What I claim as new', and desire to secure by Letters Patent, is

1. Placing the valve II in the chamber at the base ot' the nipple, when constructed and operating substantially as above described.

2. Supporting and retaining the chambers A bythe parts B, D, and U, when constructed and operating substantially as above set forth.

3. Operating the rammer by means of the lever N, said lever forming a guard for the trigger, as above described.

In testimony whereofl I have hereunto set my hand in the presence of two witnesses.

o ETH-AN ALLEN.
